From 6104984a7d1d8c17c724e799501a1be2a2a35a52 Mon Sep 17 00:00:00 2001 From: Beleswar Padhi Date: Mon, 8 Sep 2025 19:58:09 +0530 Subject: [PATCH] arm64: dts: ti: k3-am62-pocketbeagle2: Add missing cfg for TI IPC Firmware The wkup_r5fss0_core0_memory_region is used to store the text/data sections of the Device Manager (DM) firmware itself and is necessary for platform boot. Whereas the wkup_r5fss0_core0_dma_memory_region is used for allocating the Virtio buffers needed for IPC with the DM core which could be optional. The labels were incorrectly used in the k3-am62-pocketbeagle2.dts file. Correct the firmware memory region label Currently, only mailbox node is enabled with FIFO assignment for a single M4F remote core. Add the missing carveouts for WKUP R5F remote processor, and enable that by associating to the above carveout and mailbox. This config aligns with other AM62 boards and can be refactored out later.
